It is a kind of high-performance device which is used for continually producing or circularly dealing with delicate materials. In the cabined cavity, there are 1-3 sets of antithetic occludes with many layers of stator and rotor. To absorb the material, the rotor runs at a high speed to cause suction by changeable running. The material is dispersed and emulsified in shortest time by the stator and rotor step by step. The diameter of the grain becomes smaller sharply. The transmission shaft in the cavity adopts cantilever type. Flexible clutch connects the motor with the main bearing in the bearing box and improves the running quality of the transmission shaft. It is a high-performance pump with mixing, dispersing, crashing, emulsifying and transporting functions.The high shear disperser is suitable for middle or large continuous production or circularly producing process.
